<p>MultipartDemux uses the Content-type field of incoming buffers to demux and 
push data to dynamic source pads. Most of the time multipart streams are 
sequential JPEG frames generated from a live source such as a network source
or a camera.</p>
<p>The output buffers of the multipartdemux typically have no timestamps and are
usually played as fast as possible (at the rate that the source provides the
data).</p>
<p>the content in multipart files is separated with a boundary string that can
be configured specifically with the <a class="link" href="gst-plugins-good-plugins-multipartdemux.html#GstMultipartDemux--boundary" title="The “boundary” property"><span class="type">“boundary”</span></a> property
otherwise it will be autodetected.</p>
